Double-bladed manual snow removing device

ABSTRACT

This present invention is a double-bladed manual snow removing device having a front and a back blade hinged together. The blades can be opened at an acute angle or can be closed contiguously to each other. A handle, attached to the back blade, can swivel in a vertical plane. There are three ways the present device can be used to remove snow: pushing, pulling or lifting. When pushing, the front blade member pushes snow at the acute angle out of the path while the back blade member, which is the trailing blade, scrapes at any remaining snow which, when dislodged, is pushed forward by the back blade member. When pulling, it is the front blade member which is the trailing blade. With the blades closed contiguously to each other and the handle locked to the back blade, the device function as a conventional snow shovel.

RELATED APPLICATIONS

This application claims the benefit under 35 U.S.C. 119(e) of U.S.Provisional Patent Application Ser. No. 61/992,363 filed May 13, 2014,which is incorporated herein by reference in its entirety and made apart hereof.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to manual devices for removing snow and slushfrom sidewalks and driveways.

2. Description of Prior Art

Any discussion of the prior art throughout the specification should inno way be considered an admission that such prior art is widely known orforms part of common general knowledge in the field. In winter,homeowners are required to clear their sidewalks and driveways of snow.Snow accumulated on the sidewalk and driveway is usually in two layers,an upper layer that is not compacted and a lower layer that is compactedand adheres to the sidewalk or driveway. Unfortunately, most people take‘clearing’ to be shovelling which invariably leads to lifting. Liftingcan lead to a lot of health problems as this is usually done with theconventional snow shovel, which has a shaft fixed to a blade. That isthe main disadvantage of conventional snow shovels. True, some peopleuse the conventional snow shovel to push snow out of the way, but thesnow just accumulates in front of the shovel and at some point has to belifted away. The device described in this specification has two blades—afront and a back blade—hinged together with the shaft, to which the gripis fixed, rotatably connected to the back blade. This device gives theuser three options to remove snow, two of which do not require lifting.It can be configured as a plough for pushing snow, a hoe for pullingsnow and a shovel for lifting snow. There is no prior art in manualdevices for removing snow and slush from sidewalks and driveways, havingtwo blades—a front and a back blade—hinged together and with the shaft,to which the grip is fixed, rotatably connected to the back blade andwhich can be configured as a plough or a hoe or a shovel.

BRIEF SUMMARY OF THE INVENTION

The main objective of the present invention is to help users clearsidewalks and driveways of snow by pushing it to a side to the path tobe cleared, at an acute angle.

Another objective of the present invention is that in moving to and fromthe starting point of the path to be cleared, snow is pushed to the sameside of the path at the same acute angle.

Another objective of the present invention is that, when snow cannot becleared from the sidewalks and driveways by pushing it, it can be thencleared by pulling it.

Another objective of the present invention is to allow it to be used asa conventional shovel.

Method of Use

This manual snow removing device is designed primarily to push not liftsnow. The front and back blade members are made preferably of plasticwhich is corrugated so as to make them stronger and the device light.There are three ways in which snow can be removed: by pushing it, bypulling it and by lifting it.

1) When the snow on the ground is below the height of the blades of thedevice, the blades of the device are opened at an acute angle to eachother and the handle is unlocked from the back blade member so as to berotatable. The device is then pushed forward with the back bladesubstantially parallel to the user's shoulders. In pushing the deviceforward, the user uses the handle bar of the grip member.

2) When the height of the snow on the ground is above the height of theblades of the device, the blades are opened at an acute angle to eachother and the handle is unlocked from the back blade member so as to berotatable. The device is then pulled with the back blade substantiallyparallel to the user's shoulders and the front blade the trailing blade.In pulling the device, the user uses the aperture of the grip member.

3) There may be times when the user wishes to lift the snow. This isdone by locking the front and back blades contiguous to each other andlocking the handle member to the back blade member. In lifting the snow,the user places one hand on the shaft member and the other hand in theaperture of the grip member.
